• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach y ((lang xa) OR (dang xay)) hoi. lieu va cam ((duc van) or (duc va)) thanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach y ((lang xa) OR (dang xay)) hoi. lieu va cam ((duc van) OR (duc va)) thanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach y ((lang xa) OR (dang xay)) hoi. lieu va cam ((duc van) or (duc va)) thanh di cua te".
• Adding a wildcard symbol may retrieve word variants: thuat sach y ((lang xa) OR (dang xay)) hoi. lieu va cam ((duc van) or (duc va)) thanh di cua te*.
